What is the purpose of the Link Layer Discovery Protocol (LLDP)?

Explanation:
LLDP is a Layer 2 protocol designed to let network devices learn about their neighbors on the same data link. It periodically sends small frames containing a set of TLVs that share information such as the device’s identity (system name or chassis ID), the port it’s connected from, and its capabilities. This neighbor data lets network operators map the network topology, verify adjacency, and keep an accurate inventory without relying on IP addressing. Since LLDP operates at the data-link layer and focuses on neighbor discovery, it isn’t used to encrypt traffic, automatically assign IP addresses, or resolve hostnames.
